A famous Cantonese congee is called "tang jai jook" which is very popular in Hong Kong. Back in the days, the fishermen there lived in wooden boats called sampan and included peanuts, dried squid, fish slices, etc. in their congee.

You can always make this on your own and get ingredients from Hong Kong Supermarket. If not, Great NY Noodletown has a delicious one on their menu! Don't forget to order the fried crullers, a fried Chinese bread, to go along with it!
